If you're looking for a zip code for Bangor ME, you're probably realized it’s not just one number. Most people assume a city of 32,000 people would just have a single code. Nope. Bangor is actually split up more than you’d think for a mid-sized Maine city.
Honestly, it gets confusing.
The primary zip code everyone knows is 04401. This covers the bulk of the residential areas and the bustling downtown. But then there’s 04402, which is strictly for P.O. Boxes. If you’re trying to mail something to a business or a government office, you might even run into specialized codes or extensions. It’s a quirk of the USPS system that feels a bit overkill for a place where you can drive from one end to the other in fifteen minutes.
The Main Bangor ME Zip Code: 04401
04401 is the heavy lifter. If you live in a house or an apartment in Bangor, this is almost certainly your code. It covers the historic neighborhoods like the Broadway district—where you’ll find those massive Victorian mansions, including Stephen King’s famous house with the bat-themed wrought iron gates.
It also stretches out toward the Bangor Mall area and the University of Maine at Augusta's Bangor campus.
The geography here is a bit strange. The zip code follows the Penobscot River on one side and bleeds out toward the rural fringes on the other. Because 04401 is so large, the Zip+4 system becomes really important for local logistics. Without those extra four digits, mail sorting at the Eastern Maine Processing and Distribution Facility on Hammond Street would be a nightmare.
Actually, that facility is a big deal. It’s a regional hub. That means even if you're sending a letter to someone in a tiny town like Orono or Brewer, it’s probably stopping in Bangor first.
Why 04402 exists (and why you probably don't live there)
Now, about 04402. You won't find this on a map of neighborhoods. It’s a "non-geographic" zip code.
Basically, it’s for the post office boxes at the main station. If a business tells you their address is 04402, don't try to GPS it to a physical storefront. You’ll just end up at the post office counter. It’s a distinction that trips up delivery drivers all the time. Uber Eats? Doordash? They need the 04401 physical address, not the 04402 mailing address.
Beyond the City Limits: The Greater Bangor Area
People often search for the zip code for Bangor ME when they’re actually looking for the "Greater Bangor" area. Maine is funny like that—everything feels like it's part of the same town until you hit the municipal line.

- Brewer (04412): Just across the bridge. It’s practically Bangor’s twin, but it has its own identity and its own code.
- Hampden (04444): A bit more suburban/rural to the south.
- Orono (04473): Home to the University of Maine.
- Hermon (04401/04419): This is where it gets messy. Some parts of Hermon actually share the 04401 zip code with Bangor, even though they pay taxes to a different town.
This overlap is why you’ll sometimes see "Bangor" on a piece of mail for a house that is clearly in the woods of Hermon or Veazie. The USPS cares about where the mail truck starts its route, not necessarily where the city council sits.
Getting the Zip+4 Right
Look, for 99% of things, five digits are fine. But if you're dealing with the City of Bangor offices or Husson University, using the full nine-digit code helps.
The Zip+4 is a four-digit suffix that identifies a specific delivery route or a high-volume address. In a town with "Old Bangor" layouts—winding streets and weirdly numbered lots—those extra numbers ensure your package doesn't end up on the wrong porch.
Common Zip+4 Examples in Bangor:
For the City Hall at 73 Harlow Street, the full code is often written as 04401-4902.
For the Bangor Public Library, a true local gem, it’s 04401-4802.
Business and Logistics in the 04401
Bangor is the service hub for northern and eastern Maine. That means the zip code for Bangor ME carries a lot of weight for logistics. We’re talking about Bangor International Airport (BGR).
BGR is a diverted flight hotspot. Because of its massive runway—originally built for Cold War bombers—it’s often the first place international flights land if there’s an emergency over the Atlantic. The airport and the surrounding industrial park use 04401, but they have their own specific mail routing because of the sheer volume of freight moving through.
If you’re moving a business here, don’t just settle for the general code. Check with the Postmaster. You might be eligible for a unique zip if your volume is high enough, though that’s usually reserved for places like the hospital (Northern Light Eastern Maine Medical Center).
Real-World Tips for Using Bangor Zip Codes
- Verify the Physical vs. Mailing Address: If you’re sending a package via FedEx or UPS, avoid 04402. Use the physical street address and 04401.
- State Initials: Always use "ME." It seems obvious, but people still confuse it with "MD" (Maryland) or even "MA" (Massachusetts) when they're in a rush.
- The "Bangor" Label: Don't be surprised if your "Bangor" address is actually in Veazie or Hermon. Trust the zip code over the town name if they conflict on a shipping form.
- Property Taxes: Don't use your zip code to determine which school district you're in. 04401 crosses several town lines. Always check the official tax map.
Identifying the Best Neighborhoods in 04401
If you're researching zip codes because you're moving here, 04401 has several distinct vibes.
The Little City neighborhood is a local favorite. It’s walkable, filled with kids, and very close to the park. Then you have the Tree Streets, which are beautiful but can be a nightmare for parking during a Maine winter.
Further out, toward Essex Street, you get more land and a bit more privacy, while still technically being in the 04401 zone. It’s the diversity of this single zip code that makes Bangor such a fascinating place to live. You can go from a high-rise (well, high for Maine) senior living center to a farmhouse in about five minutes.
Important Contacts for Bangor Mail
If you’re having issues with delivery, the main post office is at 73 Hammond St, Bangor, ME 04401.
They handle the 04401 and 04402 routes. There is also a smaller retail location in the mall area, but for "real" mail issues—lost packages or setting up a new mailbox—Hammond Street is where the supervisors are.
Honestly, the staff there has seen it all. They deal with the influx of college students every fall and the winter storms that shut down the passes. If your mail is late in January, it’s probably not a zip code error; it’s just a blizzard.
Actionable Steps for New Residents
- Update your USPS Change of Address early. Bangor mail forwarding can take a week or two to kick in.
- Check your "Zip+4" on the USPS website. It makes a difference for insurance quotes and getting your registration stickers on time.
- Look up your specific ward. Bangor is divided into wards for voting, and these do not align with zip code boundaries.
- Double-check "Bangor Base." If you are sending something to the Air National Guard base (MAINEiacs), ensure you have the specific military mail instructions, as they sometimes have their own internal routing despite being in the 04401 area.
Knowing the right zip code for Bangor ME is the first step in navigating the Queen City. Whether you're sending a letter to a friend or setting up a new business at the Waterfront, 04401 is your go-to, while 04402 stays tucked away for the P.O. Box crowd. Keep that distinction clear and you'll avoid the most common headaches.
